HORSE-RELEASER.

SPECIFICATION forming part of Letters Patent No. 767,239, dated August9, 1904,

Application filed February 24, 1904. Serial No. 194,994.. No model.)

To all whom, it may concern:

Be it known that I, IVILLIAM WV. Posr, a citizen of the United States,residing at Valleyview, in the county of Hand, State of South Dakota,have invented certain new and useful Improvements in Horse-Releasers;and I do hereby declare'the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to horse releasers such as are employed forreleasing draft-animals from the vehicle when said animals are runningaway, the object of the invention being to provide a constructionwherein a cloubletree will be connected to the tongue in such mannerthat by pulling a string the pivot-bolt of the doubletree will bewithdrawn from the latter, and the doubletree being thus released willpass freely from the tongue of the vehicle, thus releasing thedraft-animals, it being understood that in connection with thismechanism there is to be employed some means for connecting the collarsof the animals with the forward end of the tongue which will release thecollars from the tongue when the animals pass from the vehicle.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a perspective view showing the invention applied to thetongue of the vehicle. Fig. 2 is a vertical section taken longitudinallythrough the mechanism. Fig. 3 is an elevation showing the parts in theirreleasing positions. Fig. 4: is a detail perspective view of the tubularpivot.

Referring now to the drawings, there is shown a portion of the tongue 5of a vehicle connected with the front axle 6 in the usual manner. Inconnection with the tongue there is illustrated a doubletree comprisinga central thickened portion 7 and reduced end portions 8, upon whichlatter are pivoted the swingletrees 9 in the usual manner.

The tongue 5 is thickened vertically by the upwardly-extending portion10, in which is a socket 11, through the. bottom of which is aperforation 12. The upwardly-extendingportion 10 has a passage 13extending from the 5 socket through the rear end of the projection orenlargement, and in this passage is disposed a plate or filling-block1a, the front end of which is concaved to correspond to the curvature ofthe socket. Through the filling-block 5 5 14 and the tongue 5 is formeda vertical passage 15, in which is disposed a double-ended lat-ch 17,the barb 18 at the upper end of which extends rearwardly of the tongue,while the barb 19 at the lower end extends forwardly 00 of the tongue.The latch is pivoted to the tongue and fits the passage in thefilling-block so loosely as to permit of free pivotal move ment of thelatter.

I Through the thickened portion 7 of the dou- ,5

bletree is formed a perforation 18, and the doubletree is disposed uponthe enlargement 10 so that said perforation registers with the socket inthe enlargement and in connection therewith receives the lower end andcentral 7 portion of a tubular pivot 19, the upper end of which extendsslightly above the doubletree.

To hold the tubular pivot in place, a jointed arm is provided andconsists of a rear member 20, to which is pivoted or hinged a member21,'l1aving an enlargement 22 upon its under side, in the under face ofwhich is a socket 23, which receives the upper end of the tubular pivot.A short pin 24 depends 30 from the upper end. of the socket 23 andenters the tubular pivot, the lower end of this pin 24 being beveled, asshown. A third section 25 is hinged to the free end of the section 21,and its free end is beveled, so as to fit be- 5 neathor within a housing27 in advance of the doubletree. In the section 21 of the jointed armthere is an opening 28, through which is engaged the upper end of thelatch 17 when the jointed arm is in its lowered po- 9 sition to receivein the socket in its enlargement the upper end of the tubular pivot. Inthis position of the parts the barb18 engages over the upper face of thesection 21 of the jointed arm and holds the entire arm against upwardmovement. WVhen the latch releases the jointed arm, the latter is thrownupwardly by the action of a leaf-spring 29, which is secured in theangle between the section and the tongue and presses with its free endupwardly against the bottom of the section 21.

Secured against the under side of the tongue 5, directly beneath thesection 20 of the upper jointed arm, is the section of a lower jointedarm, comprising also a section 31, hinged to the section 30 and carryingan upwardlyextending pin 32, adapted to pass through the perforations inthe enlargement 10 and the tongue 5 and into the tubular pivot, theupper end of this pin 32 being beveled to rest against and match thelower end of the short pin 24:. Hinged to the forward end ofthe section31 is a section 33, the free end of which is beveled to engage in ahousing 34:. Through the section 31 is formed an opening 35 to receivethe lower end of the latch 17,

with the barb 19 thereof engaged beneath and against the under face ofthe section 31. The latch is held normally and yieldably in engagementwith the sections 21 and 31 of the upper and lower jointed arms,respectively, by means of a spring-plate 36, secured to the under faceof the tongue and pressing forwardly against the rear edge of the latch.hen the latch is swung with its lower end rearwardly and its upper endforwardly to disengage it from the sections 21 and 31 of the jointedarms, the lower arm is swung downwardly by means of the spring-plate orleaf-spring 37, which is secured at one end in the angle between thesection 30 and the tongue and which rests with its forward end againstthe upper face of the section 31.

To disengage the latch, a cord a0 is engaged through an eye in the lowerend thereof and is passed rearwardly and then upwardly through aguide-opening 41 in the tongue and is provided with a handle 12,conveniently located to be grasped and pulled by a person occupying thevehicle.

hen the latch is actuated and the jointed arms released, the pins 2 1and 32 are drawn from the tubular pivot, and the pull on the doubletreeserves to tilt the hollow pivot from the lower socket in which it isengaged, the

forward end of the filling-block 14 swinging upwardly during thisoperation, sothat the pivot is drawn from the tongue and the dou bletreeis released, so that the draft-animals may pass freely from the vehicle.

hat is claimed is 1. The combination with a vehicle-tongue, of adoubletree disposed thereon, a sectional pin engaged through the tongueand doubletree, a latch mechanism for holding the pin in engagement withthe tongue and doubletree, and means for withdrawing the sectional pinfrom the doubletree and tongue when the latch mechanism is released.

2. The combination with a vehicle-tongue having a socket therein, of atubular pivot engaged in the socket, a doubletree mounted upon thetubular pivot, a movable arm having a socket in which the upper end ofthe pivot is removably received, a latch for holding the arm with thetubular pivot in the socket, and means for withdrawing the arm from thepivot when the latch is released.

3. The combination with a vehicle-tongue having a socket in its upperface, of a tubular pivot removably engaged in the socket, a doubletreemounted upon the tubular pivot. upper and lower arms pivoted to thetongue and having each a member of a sectional pin disposed forengagement in the tubular pivot and through the tongue, the upper armhaving a socket disposed to receive the upper end of the tubular pivot,a double latch pivoted to the tongue and disposed to engage and hold thepivoted arms with their pin-sections in the tubular pivot, meansconnected with the latch for moving it to inactive position, and meansfor moving the arms to withdraw the pin-sections from the tubular pivotwhen released by the latch.

In testimony whereof I aflix my signature in presence of two Witnesses.
